Abstract: A CRT image recording apparatus in which a picture a CRT image displayed on a CRT (16) is photographed by a camera (32). In this apparatus, the number of vertical synchronizing signals separated from a video signal is counted, and the exposure time during which the CRT image is photographed is determined so as to correspond to the number of vertical synchronizing signals 2 K ·n (where K and n are integers) thereby counted. The exposure time is therefore determined in synchronism with the vertical synchronizing signals, thereby preventing any nonuniformity of exposure from occurring on a film.

Abstract: For the thermal elimination of waste materials, such as e.g. sewage sludge, special waste or the like, use has thus far been made of conventional waste burning techniques, in particular with grate firings. Such elimination methods are ultimately not environmentally tolerable and are also not economical. In order to be able to eliminate such waste materials environmentally tolerably and yet economically, it is proposed according to the invention to burn the waste materials, possibly after their comminution and possibly after their drying or preheating in a cyclone furnace (combustion cyclone or melting cyclone of high power density), at extremely high temperatures above 1500 DEG C, forming a molten slag (18) low in harmful substances and a hot waste gas (19), in which gas the useful substances and/or harmful substances contained in the waste materials evaporate, there being separated, separately from one another, from the waste gas, in each case by partial condensation, on the one hand dusts (25) enriched with useful materials and on the other hand dusts (29) enriched with harmful substances.

Abstract: A scotch yoke compressor assembly is disclosed wherein four radially disposed pistons (96) reciprocate in cylinders defined in a crankcase (46). In a central portion of the crankcase, a scotch yoke mechanism operably couples the pistons to an eccentric portion on a rotating crankshaft (32). Each piston includes suction ports extending therethrough and a suction valve (116) on the piston head. The suction valve is operably retained on a piston head and the piston is attached to a yoke member by a single bolt (124). The bolt head is received within a recess (140) coined in a valve plate (136) interposed between the crankcase and a cylinder head cover. Circularly arranged discharge ports (143) in the valve plate are opened and closed by an annular discharge valve (146) guidedly retained against the valve plate at diametrically opposed locations, by a combination of guide pins (145) and an annular retainer member (148). The retainer member rides on the guide pins and is biased against the cylinder head cover and the discharge valve to permit extended lift during high mass flow rates and slugging.
